Nesting limit.
I haven't completely thhought it through like that, but my feeling is that it would create a giant snowball of reverse auction funds that get re re re re reversed but never awarded.
Heh, that would be interesting. Maybe you'd need a relief valve to prevent overflows. Or, to increase the complexity even more (because KISS matters so much to these people), set it up dynamically so that the fuller the curation pool, the lower the curation/author split gets, essentially to push the unused curation rewards back into the author pool.
nah its not necessary, it would eventually reach equilibrium.
so like if you started at 10000, and lost 5K to the reverse auction, the numbers would look like
10000 -5k carried over
15000 - 7.5k carried over
17500 -- 8750 carried over
18750 -- 9375 carried over
19375 -- 19687 carried over.
it would approach 20K but i think never quite get there.
KISS is a dumb idea. Some problems just don't lend themselves to simple solutions.
